- builds with CMAKE_SKIP_RPATH=ON should properly find project .so files from <build>/lib directory
- $ORIGIN doesn't work properly in cross-compilation mode
In case OPENCV_INCLUDE_INSTALL_PATH is absolute (i.e. starts with a "/"),
the path ends up with a double "/".
While this is mostly equivalent to a single slash, it may have a nasty
side effect when:
- OpenCV_INSTALL_PATH is empty
- OPENCV_INCLUDE_INSTALL_PATH is "/usr/include"
- the calling build script uses "-isystem" to specify the path to the
headers of dependencies (to avoid warnings)
Specifying "-isystem /usr/include" breaks the path ordering, and GCC can
no longer find its "stdlib.h", thus CMake filters such statements.
Unfortunately it fails to do so when using "//usr/include".
It is perfectly possible to compile ARM binaries on Aarch64. Generalize
the code to no only swap X86 with X86_64, but also ARM and AARCH64.

Adds IMPORTED for the TBB::tbb alias target as otherwise cmake produces
the following error:
CMake Error: install(EXPORT "OpenCVModules" ...) includes target "opencv_core" which requires target "tbb" that is not in the export set.
This problem occurs with the defaults used by homebrew on macOS, which
compiles both static and shared versions of TBB and OpenCV.

The Android NDK 16b has a bug that sets the ANDROID_NDK_REVISION
variable incorrectly, generating an unexpected line break in the
middle of the string. This breaks the build as the generated
version_string.inc presents an invalid C string.
Remove leading and trailing line breaks, warns for line breaks in the
middle of 'msg' and escape them before appending to
OPENCV_BUILD_INFO_STR.
- allow cmake to check sanity of vsx aligned ld/st
- force universal intrinsics v_load_aligned/v_store_aligned
to failback to unaligned ld/st if cmake runtime vsx aligned test fail
* Enabled -Wnarrowing warning
* Fixed type narrowing issues
* Cast python constants
* Use long long for python constants
* Use int for python constants with fallback to long
* Update cv2.cpp
- add infrastructure support for Power9/VSX3
- fix missing VSX flags on GCC4.9 and CLANG4(#13210, #13222)
- fix disable VSX optimzation on GCC by using flag ENABLE_VSX
- flag ENABLE_VSX is deprecated now, use CPU_BASELINE, CPU_DISPATCH instead
- add VSX3 to arithmetic dispatchable flags
* cmake: don't ignore Python from PATH environment variable
- this breaks selection between 32/64-bit Python
- this breaks Anaconda/Conda environments
- it is not the CMake default behavior, expected by many projects
* cmake: add Python version check, fallback path on CMake 3.12+
* cmake: drop Python 2.6, allow version selection for Python 3.x
Avoids passing -Wall, which will enable literally every warning in
Clang. Avoids passing -ffunction-sections etc to clang-cl, which each
generate warnings.
When cross compiling with clang, the internal C++ headers are not found
when adding sysroot to -isystem, that is redundant anyway because it
will look for headers insider --sysroot path with same quality as it
would do with -isystem otherwise
Fixes errors like

- Recommended compiler checks:
- GCC: CV_GCC
- Clang: CV_CLANG
- fixed problem with CMAKE_CXX_COMPILER_ID=Clang/AppleClang mess on MacOSX
Details: cmake --help-policy CMP0025
- do not declare Clang as GCC compiler
When compiling with OpenNI2 flag active, CMake will not be able to find OpenNI.h due to the environment path not set in OpenCVFindOpenNI2.cmake. This PR rectifies this issue.
This suppresses the interpretation of string literals by switching the ocv_download_log from a macro to a function.
This avoid crashes when the string to log contains escape characters.
More details about the problem this PR fixes are available at: https://github.com/opencv/opencv_contrib/issues/1131
- allow installing samples sources on all platforms
even if BUILD_EXAMPLES is disabled, fixed minor
issues in sources installation process
- use 'example_<group>_<name>' scheme for target and binary file naming
- use single function for sample executable creation
